A Request for Evidence, or RFE, is not a final adjudication outcome. In the employment-based petition context, it reflects the adjudicating officer’s need for a clearer articulation of eligibility, a stronger connection between the applicant’s record and the governing legal standard, or a more persuasive explanation of the applicant’s proposed work. Even when approval is ultimately secured, an RFE introduces a more demanding stage of review in which the petition must remain internally consistent and persuasive under closer scrutiny.

The following three success stories highlight approvals secured after RFE review or in the context of more complex procedural histories, consisting of two NIW approvals and one O-1A approval. These cases illustrate a range of adjudicative challenges, including extended processing timelines, cross-service-center transfers, and differences in evidentiary support.

Cases With Inherent Challenges

Extended Processing Without Premium Processing

Two of the approved cases proceeded through non-premium processing routes, with one extending to 886 days and another reaching 385 days before approval. Longer adjudication timelines increase complexity because the petition must remain persuasive over an extended period, despite potential changes in the applicant’s record or field.

Cross-Service-Center Transfers

One case involved multiple transfers between the Nebraska Service Center and the Texas Service Center before approval. This type of procedural movement requires the petition to maintain consistency and clarity across different adjudicating environments, which can increase the level of scrutiny applied.

Differences in Evidentiary Support

The cases also reflect significant variation in supporting documentation, with some filings including multiple recommendation letters, while one proceeded without any supporting letters. This range illustrates that approval after RFE review can still be achieved through different evidentiary approaches when the overall petition remains persuasive.
